📚 Past Tenses in English and German
English and German both have two main tenses for referring to past events: the present perfect tense and the simple past tense.
🎯 Regular and Irregular Verbs - Overview
For most verbs in German, you form the present perfect tense with a form of haben "to have" + the past participle of the main verb:
Some verbs use the finite form of sein instead of haben:
✅ Regular Verbs (Weak Verbs)
Formation
The present perfect tense of regular verbs is constructed by using the present tense of haben + the past participle.
You form the participle by using the stem of the verb (infinitive minus -en) and add ge- in front and -t at the end:
Complete Conjugation: spielen (to play)
| ich | habe gespielt | I have played |
|---|---|---|
| du | hast gespielt | you have played |
| er/sie/es | hat gespielt | he/she/it has played |
| wir | haben gespielt | we have played |
| ihr | habt gespielt | you (pl.) have played |
| sie/Sie | haben gespielt | they/you (formal) have played |
⚡ Irregular Verbs (Strong Verbs)
Formation
Irregular verbs form their past participle in most cases by adding ge- to the stem and -en at the end:
Common Irregular Verbs
| finden | gefunden | to find |
|---|---|---|
| helfen | geholfen | to help |
| schreiben | geschrieben | to write |
| trinken | getrunken | to drink |
| sehen | gesehen | to see |
| sprechen | gesprochen | to speak |
🔄 Mixed Verbs
There is also a group of verbs (often called mixed verbs) which have a stem change but add -t instead of -en:
| bringen | gebracht | to bring |
|---|---|---|
| denken | gedacht | to think |
| wissen | gewusst | to know |

| reisen | gereist | to travel |

| bleiben | geblieben | to stay |

🔑 Present Perfect of haben and sein
As auxiliary verbs, haben and sein play an important role in forming the present perfect tense. But it's also important to know their participle forms:
⚠️ Special Cases to Watch Out For
- Verbs with Stem Endings in -d or -t
Verbs whose stem ends in -d or -t need an extra -e to form the participle:
- Verbs with Inseparable Prefixes
Verbs with an inseparable prefix such as be-, er-, ver-, zer- do NOT put ge- in front:
| bezahlen | bezahlt | Regular |
|---|---|---|
| verkaufen | verkauft | Regular |
| verlieren | verloren | Irregular |
- Verbs Ending in -ieren
Verbs ending in -ieren also do NOT add ge- at the front:
- Separable Verbs
Separable verbs form the past participle like other regular or irregular verbs, but the prefix stays at the front:
| Regular | prefix + ge + stem + t | aufmachen → aufgemacht |
|---|---|---|
| Regular | prefix + ge + stem + t | einkaufen → eingekauft |
| Irregular | prefix + ge + stem + en | aufstehen → aufgestanden |
| Irregular | prefix + ge + stem + en | fernsehen → ferngesehen |

|---|---|---|---|
| Irregular | haben | ge + stem + en (vowel change) | gesehen, getrunken |
| Mixed | haben | ge + stem + t (vowel change) | gedacht, gewusst |
